Using the White Balance
This button is available only when using a Color camera. White Balance allows you to “color
correct” the camera for changes in lighting or camera sensor temperature. Click the “Set White
Balance” button, and draw a rectangle on a white area in the image. You should use an area that is
colored white. You should not use an area that is overexposed
Using the Internal Timer
If you are using the internal timer, and processing a complex application, you may need to in-
crease the Trigger Source slider to avoid skipping parts. It is sometimes a good idea to start with a
slow time during setup, say 100 ms, and then optimize it when the application is complete. First
save your Solution with the internal timer set to the longer time interval, then go back and try
adjusting the time to a smaller interval. Notice the Parts Skipped counter on the Monitor panel. If
your time interval is too small, parts or images may be skipped.
Using the External Trigger
If you are using a part-in-place sensor, and your part does not appear in the image area, you may
need to use the inspection trigger delay to compensate for any small time difference between
when the part is under the part-in-place sensor and when the part is actually in front of the camera
lens. If the image is blurry, you need to use the Exposure control to sharpen the image quality.
Using the Exposure Control
The Exposure setting indicates the approximate exposure time. The slider range changes to
match the programmable range of the camera. For fast moving parts, you must have a very low
exposure time, and a very bright light source.
NOTE The time between external triggers, or the internal timer setting, must be larger
than the Exposure Time plus the Image Acquire Time (frame time) plus the Trig-
ger Delay. The Exposure setting will override the Internal Timer setting, if this
condition is not met.
